“/”应用程序中的服务器错误。--------------------------------------------------------------------------------未能加载文件或程序集“Oracle.DataAccess”或它的某一个依赖项。找到的程序集清单定义与程序集引用不匹配。 (异常来自 HRESULT:0x80131040) 说明: 执行当前 Web 请求期间，出现未经处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。 异常详细信息: System.IO.FileLoadException: 未能加载文件或程序集“Oracle.DataAccess”或它的某一个依赖项。找到的程序集清单定义与程序集引用不匹配。 (异常来自 HRESULT:0x80131040)源错误: 执行当前 Web 请求期间生成了未经处理的异常。可以使用下面的异常堆栈跟踪信息确定有关异常原因和发生位置的信息。  程序集加载跟踪: 下列信息有助于确定程序集“Oracle.DataAccess”未能加载的原因。警告: 程序集绑定日志记录被关闭。要启用程序集绑定失败日志记录，请将注册表值 [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD)设置为 1。注意: 会有一些与程序集绑定失败日志记录关联的性能损失。要关闭此功能，请移除注册表值 [HKLM\Software\Microsoft\Fusion!EnableLog]。堆栈跟踪: [FileLoadException: 未能加载文件或程序集“Oracle.DataAccess”或它的某一个依赖项。找到的程序集清单定义与程序集引用不匹配。 (异常来自 HRESULT:0x80131040)][FileLoadException: 未能加载文件或程序集“Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342”或它的某一个依赖项。找到的程序集清单定义与程序集引用不匹配。 (异常来自 HRESULT:0x80131040)]   System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks) +0   System.Reflection.RuntimeAssembly.nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks) +39   System.Reflection.RuntimeAssembly.InternalLoadAssemblyName(AssemblyName assemblyRef, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection, Boolean suppressSecurityChecks) +132   System.Reflection.RuntimeAssembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection) +144   System.Reflection.Assembly.Load(String assemblyString) +28   System.Web.Configuration.CompilationSection.LoadAssemblyHelper(String assemblyName, Boolean starDirective) +46[ConfigurationErrorsException: 未能加载文件或程序集“Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342”或它的某一个依赖项。找到的程序集清单定义与程序集引用不匹配。 (异常来自 HRESULT:0x80131040)]   System.Web.Configuration.CompilationSection.LoadAssemblyHelper(String assemblyName, Boolean starDirective) +618   System.Web.Configuration.CompilationSection.LoadAllAssembliesFromAppDomainBinDirectory() +209   System.Web.Configuration.CompilationSection.LoadAssembly(AssemblyInfo ai) +130   System.Web.Compilation.BuildManager.GetReferencedAssemblies(CompilationSection compConfig) +178   System.Web.Compilation.BuildManager.GetPreStartInitMethodsFromReferencedAssemblies() +94   System.Web.Compilation.BuildManager.CallPreStartInitMethods() +332   System.Web.Hosting.HostingEnvironment.Initialize(ApplicationManager appManager, IApplicationHost appHost, IConfigMapPathFactory configMapPathFactory, HostingEnvironmentParameters hostingParameters, PolicyLevel policyLevel, Exception appDomainCreationException) +591[HttpException (0x80004005): 未能加载文件或程序集“Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342”或它的某一个依赖项。找到的程序集清单定义与程序集引用不匹配。 (异常来自 HRESULT:0x80131040)]   System.Web.HttpRuntime.FirstRequestInit(HttpContext context) +8946548   System.Web.HttpRuntime.EnsureFirstRequestInit(HttpContext context) +97   System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +256

在此服务器上查找运行成功项目，查看其web.config中如下节点

<?xml version="1.0" encoding="UTF-8"?><configuration>  <runtime>    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">      <dependentAssembly>        <assemblyIdentity name="Oracle.DataAccess" publicKeyToken="89B483F429C47342" culture="neutral" />        <bindingRedirect          oldVersion="4.112.3.0"          newVersion="2.102.2.20"/>      </dependentAssembly>    </assemblyBinding>  </runtime></configuration>

拷贝到 oldVersion=”4.112.3.0” newVersion=”2.102.2.20”
覆盖到失败项目中去（oldVersion，newVersion具体值以项目中的值为准）

分析原因：项目工程应用oralce dll版本有所区别导致的
